Genuine E3D Hardened Steel Nozzle V6 (1.75mm) 0.40mm (V6-NOZZLE-HS-175-400)

I replaced a brass nozzle a while back and have not noticed any issues with this replacement. Seems to be working as designed.

I’m so glad that this compatible with my Prusa mini+. It was easy to install and calibrate for the first layer test.

This is really well made as expected from E3D. In warmer weather, I was printing everything normally, maybe adding 5 degrees to the standard filament settings in my slicer to compensate for the steels lower heat transfer, and was planning to just leave this on permanently. But as colder weather has set in and the ambient temperature in the room has cooled off, Ive had a lot of issues with clogging even at 20 degrees or more above the original settings, especially in prints with large flat areas. This can also be compensated for by slowing down to allow the steel nozzle more time to heat the filament but personally, Im switching back to brass for the winter.

I have a Prusa MK3 and decided to grab a steel nozzle for more abrasive filaments. So far this steel nozzle has been working great. It was a quick install from my .4 brass stock nozzle. But ive had no issue with extrusion or clogging at all. The only issue ive had was operating temps. I have to go up as much as 20c to get this to print as well as my brass one. But other than that, its been a great nozzle. I highly recommend it for your E3D hotend.

This nozzle has been great so far.

The nozzle prints quite nice at slow speeds under 80 mm/s. Unfortunately due to my specific setup (LDO 2504AC) I get some massive VFA when I print less than 200 mm/s and a ton of resonance at 60-110 mm/s (I normally push 228 with nickel plated copper). This has led me to raising abs temps from 265 to 290 to compensate but it just doesn’t want to flow right and adhere at those speeds due to it being steel and me now just learning about this (oops). A better fit for me would be a tungsten nozzle. Not really the nozzle’s fault because it is tough as nails and survived a slow bed crash and the blob of death along with a ton of brass brushing. I’ll just keep it around as a spare because it’s part of the funny history of my printer now.

quality nozzle must have for abrasive filaments last forever with normal filaments

Likely received a defective nozzle. Nozzle is either extremely poor at conducting heat or inner diameter is far smaller than advertised. Underextrusion perpetually to the point where extruder motor is clicking from gears slipping due to too much resistance. Though it improved the higher the temp got ( up to 260* c for PLA!) I found no way to compensate in order to make this functional for any print.

Used it with abrasive and non abrasive filament. Did not have to adjust temperatures for either type compared to brass nozzle.

I have a Creality CR-5 Pro H and this thing has been printing beautifully with high temp ASA
